Gale Price and Nicola Main are agents with N.O.O.D.L.E.S.
That rather odd acronym stands for the National Organization for Order, Discipline, and Law Enforcement in Schools. Its purpose is to ensure that that day-to-day running of the many seats of learning across the United Kingdom is not interrupted by underhanded individuals with shady plans of their own. From the number of operatives scattered across the nation in small bases or on assignment at the various facilities being protected, there are a good deal of shenanigans taking place all the time. Some of these illegal activities are quite vicious and sometimes lethal.
Running the entire operation is an elderly grandmotherly-type lady known only as Miss "Z". This white-haired bespectacled apparent spinstress might at times appear a doddering old lady but she runs a very tight and highly state-of-the-art technological agency, complete with a sophisticated control center where each of the active operations are monitored 24/7.
The exact age of the two young ladies whose adventures comprise those of "The Girls From N.O.O.D.L.E.S." is not stated but is likely to be 15 or 16, probably the latter. The two are obviously best of friends based on how close they act and how concerned they are for each other, though they do not let that interfere with getting the mission down correctly.
Both Price and Main are highly athletic individuals, vital for carrying out some of the assignments they are given. Running long distances, swimming, and mountain climbing are but three of the physical activities they will be called upon to perform. Skills with the use of various weaponry including archery and handguns are honed during the times they are not actively in the field.
Price is a brunette and appears to be the one more likely to come up with the plan of action used. The blonde Main is the more cerebral and does the majority of research in preparation for the missions. Both are adventurous and gutsy and quite capable of taking care of themselves and each other.
